BsrLIENT WHEEL Tohllwwmit may concern:

Beit known that we, VILLIAM WELSH and WILLIAM Pernis, subjects of the British King, residing at Glasgow, Scotland. have invented certain new and useful Improvejments in Resilient. yVi'heels; and Vive do here- .'b v declare the following to be a full. clear.y

and exactV description of the invention. such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to resilient wheel,"y

of the. type wherein the rim of the wheel made up from a number of sections movahlv jointed tt'igether and supported on the nave of the Wheel h v means of spring spokes and the invention has for its object to improve theconstruction of such wheels.-

Under the present invention each rim seetion has secured thereto spoke members or pins which are. capable. of 'being readily adjusted in such manner as to var)Y the coni pression of the springs in the .spokes and' the rim' sections of the wheel are secured together h v means of improved jointing arrangements.

In order that the invention ma;v he clearl)v understood We have hereunto appended Yexplanatory drawn-lgs vvhereon- Figure l shows a parto the Wheel partly in section and partly in side elevation. Fig. Q shows a slightly different construction of the Wheel. Fig. 3 is a cross section of the rim and tire. Fig. 4 shows a method of hinging the rim sections together.

lncarrying ont our invention the felly or rim o of the Wheel is madein segments provided vvit-h screwedsocliets e which point radially toward the center of the vvheel and which are each adapted to receive the screwed end of a pin (Z. Each ot the pins ri when screwed into place projects radially toward the center of the wheel. Each spoke e of the Wheel is made with a socketat its outer end and into this socket a spring,r r/ is inserted and the pin projecting radially from the underside of the folly or rim, is adapted Yto enter the socket and lbear on the top of the spring:l therein the lower end of the spring hearing on a stop f in the-socl et. The s olies may be tubular as shown at Fie. 1,"andiopenlattheir outer ends for the reception of the ins which latter. are each vpartly threade and partly smooth, the
